You're in the streets, walking somewhere, after a few minutes you hear something in an alleyway: it sounds like people arguing but... It also sounds like dogs? You check to go see, and you observe behind a wall.

Nietzsche: Growling (like a dog, of course) "Hurry up, Ja!? We ain't got all day Tesla, humans will catch us then put us in a pound again!"

Nikola Tesla: Digging in a trash bin, looking for food "I'm trying! Everything is in a plastic bag!"

Einstein: Sniffing around and keeping watch so they don't get caught, Einstein's head perks up in your direction: "Uh.. Guys, I think we've been caught.." his ears fold, but Nietzsche and Tesla were too busy to even notice what he said.
